Application filed July 1.

This invention relates to retaining devices and has for its general object the provision of a device adapted to be mounted upon a door and operable to hold the door 5 in any desired position so that closinglor slamming equipped with spring means operable to re tain the lever selectively in operative or inoperative "position, the arrangement of the parts being such that shifting from one position to the other maybe efiected by com- 'paratively light pressure'hy the opera-tors foot.

Another object of the invention is to providea device ofwthischaracter having a movablymounted' anchor "member on the spring tensionmeans, thefa-nchor member ing membertor maintaining the latter in se- V leo'tedpositionv I shifting in accordancewith the position of the holding arm or lever so as to be past center with respectto the pivot l of the hold- Yet 'another object is i the provision of guide means on the frame of the device and on the holding member, the guide means '00- operating to prevent bending or otherdistortion or displacementof the holding memher when in use. a I

"The inventionftur-ther contemplates the provision of-a device oif-this character which consists-otthe minimum number of parts whereby 1 it will be inexpensive-' to -manutactu-re, easy to install and also neat in appearance as well as easy to operate, efficient and durable in service, and=a general improvement in the art.

iTo't-he attainment of the foregoing and other objects and-advantagesthe invention consists in the details of construction-and the arrangement and combination of parts to be hereinafter more fully "described and claimed and illustrated in the accompanying drawings in whichr Y Figure 1' isa fragmentary elevation of :the lower portion o'fa door and itsjamb showing the invention applied and in inoperative or released position,

Figure 6' is :a detail section through the floor engaging cup.

' Referringmore-part cularly to the draw-- 1 tterA'designates a door'cooperating with a jamb Band C represents the floor on-which is mounted the door sill '1) located within'the lower opening. v v

In carrying out the inventionI provide a frame 10 or any desired" si'ze,-shape and material, finished or treated in any preferred manner to have a neat and attractive appearance. In the present instance this frame is-represented as being of elongated rectangular form with'the corners rounded and formed with suitable-holes 11 through whichare passed screws 12'or the like whereby the frame maybe secured- =upoi1 the door near the lower edge thereof. The end por tions of this irame'are'iormedwith openings 13- and 14, 'the'tormer of which has its outermost edge '15 curved' and the latter of i' which has its inner-edge 16 [curved and"- formed with; a projection l7--for a purpose t be described. 1

The nu-mer'al'18 designates the :movable floor engaging armor lever which may conveniently be formed either as a castinger stamping and which is ot-elongated formation preferably channel shaped in I cross section -as clearly indicated-in Figure 5. 'In-. term-ediate its ends this member l8is formed with a lug orear 19 disposed against the outer side of the intermediate portion of the frameand pivoted thereto as byabolt, rivet or the like indicated-mat 20. The above described curved edges and-16 of the open ings in the frame-are str'uokatrom the pivot point 20 as a center. At its ends the movable member 18 is formed or-otherwise .provided with upstandingprojections-21' and 22- which :have their upper surfaces prsferably ridgedfor toothed as shown to avoid slipping when engaged bythe operators footduring the act of moving the member 18linto'one position or the other.

{Mounted at one end of the member 18 isthe floor engaging-element 23 formed preferablyas a 'oupot' rub-ber held in position in" any-desiredmanner as for instance by means of a--screvv24athreaded into the member 18 and passing preferably through .a washer25 within thecup'. This member '23 is designed to bear upon the. surface of the floor when the device is in operative position and it will be noted that it will have a sort of suction cup action insuring a firm hold on the floor.

To apply the necessary tension to the member 18 for holding it in operative position and also for holding it in released position, I employ an elongated coil spring 26 of any desired strength, which spring has one end connected with a' transverse pin 27 or the like extending through the member 18. The other end of the spring is connected with a lateral lug. 28 on the free end of an arm 29 pivoted on the bolt 20. The lug 28 is disposed outwardly of and inslightly spaced relation to" the curved edge 16 of the opening 14 and is engageable with the projection 17 which serves as a stop for limitin movement of the arm 29 in one V o b L 1 I n direction. Movement in the other direction is limited by engagement of the lug 28 with the upper edge of the opening 14. To accommodate the lug 28 thc memberlS may have its side toward the frame notched as shown at 30. 1

At the curved edge 15 of the opening 13 is provided a flange 31 engaged by an overhanging hook 32 on themember 18, this de tailed construction being of importance in that bending or displacement of the member 18 with respect to the frame will be prevented. Furthermore the flange 3l and hook 32 coact to define guide means for the member 18 throughout its movement in either possible direction,

Assuming that the device has been constructed, assembled and applied to a door, it will be seen that when the device is in in operative position the parts are arranged as in Figure 1, the member 18 being then in substantially horizontal position and maintained so by the spring. 'At such a time the suction cup is of course out of engagement with the floor and the door may be moved freely in the ordinary manner. At this time the arm 29 is in its uppermost or upwardly swung position with the lug 28 engaging against the upper edge of the opening 14. When the arm is in this position the spring lies above the pivot bolt 20 and its tension acts to maintain the member 18 in its horizontal position.

To render the device operative, it is merely necessary for the operator to press his foot upon the projection 22 and force this end of the member 18 downwardly. During this movement the. tension of the spring upon the arm 29 will cause the latter to swing downwardly into the position shown in Figure .2, the lug 28 engaging against the projection 17. The shifting of the position of the arm 29 results in bringing the spring to a position entirely below the pivot 20 so that the tension of'the spring will hold the suction cup 23 in firm engagement with the Attention is directed to the fact that there i is only one moving part at the front-ofthe frame, the frame being peripherally. flanged as shown so as to define a speci'es'of housing within which the arm 29 operates while concealed from view. .When the member 18 is in its inoperative .or horizontal position it serves as a housing for the spring which is almost entirely enclosedtherein', as shownin Figure 1. For the sake of lightness the framemay be of an extremely skeleton-like form, if preferred, though this is a matter which may be varied to meet the wishes of the manufacturer. I

lVhile I have shown and described the preferred embodiment of the invention, it, should be understood that the disclosure is merely illustrative as I reserve the right to make all such changes in the details and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.
